Thanks all. Phew... I'd rather not inject simply from a safety point. A bit worried about getting out of the farrowing area super quickly if they squeal and Mum isn't happy about it

. Our hurdles are high and I'm not errrrrr....let's say, overly agile

. The parting words of that American pig farmer I met yesterday were.....'just remember, they are HER piglets, not yours. They squeal, get out, quick'

I'll get digging tomorrow. make a nice big mound to tip in a bit everyday.
